Band Protocol

We see it all the time—models arrive at our lab with bands that are out of position.

 

This usually happens when the bands are placed incorrectly in the impression or “float” during the impression or pouring process. When this occurs, we often need to request a new impression, or we have to duplicate the model and transfer the bands. Unfortunately, duplicating models in these cases is not ideal—it often reflects the inaccurate band placement, and carving is required to compensate.

 

While many providers were taught in dental school to take impressions with bands in place—commonly known as pick-up impressions—this method relies heavily on perfect conditions. And as we all know, things aren’t always perfect.

 

As a lab owner with over 29 years of experience, I want to share a simple, effective technique that consistently delivers more accurate results, saves valuable chair time, and avoids the need to ask patients to return for repeat impressions.

We encourage you to give this approach a try!

 

Recommended Protocol

1. Take accurate impressions using a high-quality impression material. Check carefully for defects or distortions.

2. Fit the bands to the patient’s teeth.

3. Remove the bands, rinse thoroughly, disinfect them, and allow them to dry.

4. Replace separators in the patient’s mouth.

5. Tape the bands securely to the RX Form, or place them in a labeled envelope and staple it to the RX Form.

6. Carefully wrap the model or cast, and package it along with the bands and RX Form before sending it to our lab.

 

Once we receive the case, our technicians will carefully score the model and seat the bands with precision. There is no additional fee for this service, and we guarantee it will be correct every time.

 

If we receive a case where the bands appear out of position, we will notify your office and offer two options:

• Retake the impression for maximum accuracy

• Allow us to create a duplicate model and transfer the bands (a nominal fee applies)

Please note: we cannot guarantee appliance fit on duplicate models, though we will always do our best to ensure the best possible outcome.

 

I understand this might be different from what you’re used to—but I encourage you to give it a try. As one dentist once told me, if technicians don’t share more effective methods, we’re doing a disservice to the doctors we work with. We’ve promoted this protocol for over eight years, and every practice that has tried it has stuck with it—every single one.
